My ELO in Trajan is 2073 and I just defeated someone with an ELO of 1617, but didn't gain any ELO points. I have nothing to gain, but lots to lose? How do I know exactly how low to set my bracket minimum when setting up a new game in the waiting room, as to make sure I will gain at least some points if I win?

I'm not surprised since I think that, with an Elo gap of +456 (2073 - 1617), you are likely to win 1 point at best for any victory, and most probably 0 through the rounding algorithm...

In a 5-years old dedicated post (the title can be translated as "Modification in the Elo calculation"), unfortunately written in French, Diplojak writes (excerpts from 3 different coms) :

Translation (hopefully correct) :... It's a classical Elo calculation, the same that was used in France for chess tournaments (by FFE, French Chess Federation) before the FIDE formula (= WCF, World Chess Federation). That's just a bit long to be detailed here ...... A player ranked Elo 1500 beats a player ranked 1400 : roughly, to modify the Elo in a 2-players game, you give the current Elo a weight of 15, and to the gain [*] linked to victory (evaluated to something like 1800 in this example) a weight of 1 : ((1500 x 15) + (1800 x 1)) / 16 = 1519 ...... the points you win, using a ponderation or not, and whichever the number of players is, tends towards 0 when the gap [**] gets closer to 400 points ...

It may happen if someone is replaced in a game as well : he will not count for ELO variations. si if in a 2p game, one is a replacement, the other will not count for ELO because he has no ELO opponent.

Sorry, but with an Elo gap >>+400, I don't think you need to be in a "friendly game" to win 0 Elo points in case of victory (see my com above)

Against Mat76 I win 2 ELO at each victory at Rallyman (around 400 ELO diff)I think, that the minimum is 1, not 0
